Application filed December 26, 1912. Serial No. 738,678.

To all whom it may concern Be it known that I, ALEXANDER Mo- Kivion'r, a citizen of the United States, residing in Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Sound- Preventing Means, of which the following is a specification.

My invention relates to means for practically' preventing any sound in the use of chamber vessels and the like, a urinal. The embarrassment and annoyance often caused by the noise incident to the use of such vessels is a matter of common knowledge. Various devices to meet this condition have been proposed, such as specially constructed vessels, or an attachment to be removably secured to the vessel. Such devices have not proved entirely effective as sound deadeners and also being unsanitary or difficult to keep clean, and more or less expensive, have not proved asuccess.

My invention is designd to overcome the above-noted objections, andto provide asimple, efiective, inexpensive and practical device for the purpose indicated.

My invention involves the principle of using a float which is non-resonant, and also free from actual contact with the containing vessel, so that it cannot transmit sound vibrations thereto, and which will also rise with the liquid in the vessel and thereby always remain in proper position, relative to the liquid.

Other objects of peer, hereinatter.

In'the accompanying the invention will apdrawings, Figure 1 chamber-vessel and a float combined therewith in accordance with the 'prinoiples of my invention; Fig. 2 is a simila'r view of the invention adapted to a water-closet.

Referrin to Fig. 1, a vessel A which may beof usua and well-known construction, contains a float B which may appropriately be termed a muffler float. The float is preferably in the form of a disk, flat on the bottom, but having'a conical or convex upper surface. As shown, the upper face is inclined downward or tapered from the cento the circ ierence. The vessel A is fcraiedwith substantially yerti e of such size as I walls, and the float road to provide only a slight clearance between it and the wells of the vessel. Thus formed,

when used as IHZKES an edective liquid-proof coating, is

or the water. In

heneath the rim it serves, in addition to its function as a sound deadener, as a cover for the liquid and reduces the evaporation of the liquid and the escape of odors.

The iloat may material, such as wood, cork, sheet metal made into a hollow disk, etc, but I prefer to .nia-lreit of wood impregnated or coated with some waterproof material. I have found that ordinary pitch is well suited for this purpose, as it is cheap, easily applied,

not afiected by the urine, and as it forms a smooth, glossy surface to which the liquid will not'adhere, is sanitary and easily kept clean. It is applied by dipping the disk of wood in the hot pitch.

The float always remains on the surface of the liquid, and being formed of nonresonant material, a stream of water falling thereon is practically noiseless and runs ofr" the edge of the float into the body of the liquid without. splash or noise. For convenience in removing or handling the float, achain or cord 2 may be attached thereto, and hang over the edge of the vessel. A weight 3 may be secured to the chain if desired, but is not usually required. A covering oi water-prooi fabric 7 or the like, may he secured to the surface of the float if desired.

in 2 l have shown my invention adapted to a water-closet G. The chain 2 in this instance extends through the usual space t provided. by the rubber stops for the cover 5. the closet is used as a urinal, the float "5 remains on the surface of the liquid, or by means of the chain. inclined position with the front edge up out this position it is adapted for use as a urinal for either sex when seated. in this forward position it does not interfere'with the use of the toilet for other urposes. When it isldesired to flush the toilet, the chain may be pulled out farther to carry the forward edge of the float up into engagement with the shoulder 6 formed of the howl and tilt 'the iioat about the point 6 as a fulcrum. into a position that will not interfere with the flushing of the closet.

it will he noted that the float B does not require or form a part of any specially constructed vessel or urinal, out is adapted for the forms of vessels in common use.

so as to assume an be made of any suitable the float may he pulled forward 9 thereof andextending overthe edge of the I wish not to be limited to the particular forms of float and containing vessels herein shown, as the float is adapted to a more general use and various modifications in the form, materials used, and method of manufacture, might be made Without departing from the spirit and scope of my invention.

l/Vh'at I claim as new and desire to secure by Letters Patent of the United States is 1. The combination of an open vessel forming a urinal, a sound preventing device substantially covering and forming a cover for the liquid in the vessel and free to rise as the, liquid in the vessel rises, and means attached to said device adjacent one edge vessel to form afhandle for manipulating Gopie: of thin patent may be obtained for maaeao name to this specification in the presence'of two subscribing Witnesses.
